refactor(crash): Improve crash report payload and reduce cooldown

This commit refactors the crash reporting mechanism with two key improvements:

- The cooldown period for sending crash reports has been reduced from 4 hours to 2 hours, allowing for more timely feedback. This was achieved by replacing the hardcoded millisecond value with `TimeUnit.HOURS.toMillis(2)`.
- The JSON payload for the crash report has been updated. The generic `"thread": "main"` and `"message": "App crashed"` fields have been replaced with a more specific `"namespace": packageName` field, providing better context for debugging.
